Dual-venc 4D flow MRI has previously been reported to achieve wide velocity dynamic range while maintaining a high velocity-to-noise ratio, which is particularly relevant for neurovascular applications. To increase flexibility in spatiotemporal resolution, we present a prototype implementation of a interleaved 8-point dual-venc 4D Flow acquisition with independently prescribed (prospectively undersampled) spatial resolution of the high venc acquisition, i.e. Variable Spatial Resolution Dual Venc (VSRDV). This allowed anti-aliasing error rates less than 15% error for a high venc spatial resolution of 70-80%. This represents 10-15% reduction of scan time.
